CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a Continuation Application of U.S. patent application Ser. No. 16/388,059, filed on Apr. 18, 2019, and is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application Serial No. 10-2018-0057208, filed on May 18, 2018, in the Korean Intellectual Property Office, the entire disclosures of which are incorporated herein by reference.

BACKGROUND 1. Field

The present disclosure relates generally to electronic devices that adjust the position of content displayed on a display and methods for operating the same.

2. Description of Related Art

As electronic devices are highly integrated, and high-speed, high-volume wireless communication technology advances, electronic devices come equipped with various functions. For example, electronic devices come with integrated functionality, including entertainment functions, such as playing video games, multimedia functions, replaying music/videos, communication and security functions for mobile banking, and scheduling or e-wallet functions.

Advancing display and battery performance has led to the development of more compact and portable electronic devices. For example, head-mounted or other various wearable electronic devices are being introduced.

Recently, electronic devices are providing more diversified services and additional functions. Also being developed is a diversity of applications runnable on portable devices. Head-mounted devices, wearable devices, or other various portable electronic devices are coming into use to meet user demand.

A head-mounted portable device may display augmented reality (AR) images. A head-mounted portable device may output an AR image in an unchanged display region regardless of ambient illuminance or movement speeds.

The user's view angle may be varied by ambient illuminance or movement speeds due to differences in features between the periphery and center of the retina. For example, the user may need to shift their gaze to a display region where an image is output as ambient illuminance or movement speed varies. When no change is made to the image due to ambient illuminance or movement speed, the user who steadily gazes at the AR image may suffer from fatigue, pupil damage, or other safety issues due to a delay in gaze shift.

The electronic device 201 may adjust the position and/or size of the content displayed through the display 260 to minimize a shift of the user's gaze due to a change in the ambient illuminance ambient illuminance speed.

FIG. 3 is a diagram of a configuration of an electronic device 301, according to an embodiment.

Referring to FIG. 3, the electronic device 301 may be implemented in substantially the same or a similar manner to the electronic device 101 or 102 of FIG. 1 or the electronic device 201 of FIG. 2. The electronic device 301 may include at least one of a sensor module 310, a processor 320, a memory 330, a display 360, or a communication module 390.

The sensor module 310 may detect the state of the electronic device 301. The sensor module 310 may be implemented in the same or a similar manner to the sensor module 176 described above in connection with FIG. 1. The sensor module 310 may detect the ambient illuminance and/or speed (or acceleration) of the electronic device 310. The sensor module 310 may include an illuminance sensor 312, an acceleration sensor 315, and a global positioning system (GPS) module 317.

The illuminance sensor 312 may detect the ambient illuminance of the electronic device 310. The illuminance sensor 312 may detect the ambient illuminance of the electronic device 310 and transmit a signal corresponding to the detected ambient illuminance to the processor 320.

The GPS module 317 may obtain information about the position of the electronic device 310. The processor 320 may determine a variation in the position of the electronic device 310 based on the position information received from the GPS module 317.

The processor 320 may control the overall operation of the electronic device 301. The processor 320 may be implemented in substantially the same or a similar manner to the processor 120 of FIG. 1.

The processor 320 may display images (or content) stored in the memory 330 through the display 360. The processor 320 may display images (or content) using augmented reality technology. The processor 320 may adjust the position and/or size of the image (or content) displayed using augmented reality technology according to the ambient illuminance and/or speed of the electronic device 301 obtained using the sensor module 310.

The processor 320 may adjust the position of the output of content displayed on the display 360 according to the ambient illuminance of the electronic device 301. The processor 320 may adjust the position of the output of content to the left or right.

When the illuminance is higher than a designated illuminance, the user's field-of-view may be wide and, thus, the processor 320 may adjust the position of the output of content so that the content is output in the display region corresponding to the wide field-of-view. Further, the processor 320 may output the content with a shorter focal length than when the illuminance is lower. When the illuminance is lower than the designated illuminance, the user's field-of-view may be narrow and, thus, the processor 320 may adjust the position of the output of content so that the content is output in the display region corresponding to the narrow field-of-view. Further, the processor 320 may output the content with a longer focal length than when the illuminance is higher.

The processor 320 may identify the ambient illuminance of the electronic device 301 using the illuminance sensor 312. The processor 320 may display content in the display region corresponding to the range that includes the identified illuminance based on the identified illuminance. When the identified illuminance is within a first illuminance range, the processor 320 may designate the position of display of the content as at least part of a first display region. When the identified illuminance is within a second illuminance range, the processor 320 may designate the position of display of the content as at least part of a second display region. The first display region and the second display region may mean regions included in the display 360. The first display region and the second display region may mean regions when an image and/or object is displayed using augmented reality technology. The first display region and the second display region may have different view angles (or fields of view) and/or focal lengths. When the second illuminance range corresponds to an illuminance higher than the first illuminance range, the first display region may correspond to a first FOV, and the second display region may correspond to a second FOV wider than the first FOV.

The processor 320 may adjust the position of the output of content displayed on the display 360 according to the speed of the electronic device 301. The processor 320 may adjust the position of the output of content to the left or right.

When the speed is lower than a designated speed, the user's FOV may be wide and, thus, the processor 320 may adjust the position of the output of content so that the content is output in the display region corresponding to the wide FOV. Further, the processor 320 may output the content with a shorter focal length than when the speed is higher. When the speed is higher than the designated speed, the user's FOV may be narrow and, thus, the processor 320 may adjust the position of the output of content so that the content is output in the display region corresponding to the narrow FOV. Further, the processor 320 may output the content with a longer focal length than when the speed is lower.

The processor 320 may identify the speed of the electronic device 301 using at least one of the acceleration sensor 315 and the GPS module 317. The processor 320 may display content in the display region corresponding to the range that includes the identified speed based on the identified speed. When the identified speed is within a first speed range, the processor 320 may designate the position of display of the content as at least part of a third display region.

Referring to FIG. 6, at step 601, the processor 320 may identify the ambient illuminance of the electronic device 301 using the illuminance sensor 312.

At step 603, the processor 320 may compare the identified illuminance with a designated illuminance. The processor 320 may determine whether the identified illuminance is higher than the designated illuminance. The designated illuminance may be set by the user or automatically by the processor 320.

At step 605, when the identified illuminance is higher than the designated illuminance, the processor 320 may change the position of the virtual image corresponding to the content to a first display region having a broader view angle or FOV. The processor 320 may change the position of the virtual image corresponding to the content to the outside of the user (e.g., away from the center axis of the user's FOV). In order to change the position of the virtual image corresponding to the content, the processor 320 may adjust the position and/or size of the content displayed on the display 360. The processor 320 may change the position of content displayed through the display 360 to an outside region. The processor 320 may increase the distance between the image for the left eye corresponding to the content and the image for the right eye corresponding to the content. The processor 320 may display content with a shorter focal length than when the illuminance is lower.

When the identified illuminance is higher than the designated illuminance, the processor 320 may output the image not in a first region but in a second region that has been further expanded compared to the first region.

At step 607, if the identified illuminance is not higher than the designated illuminance, the processor 320 may determine whether the identified illuminance is lower than the designated illuminance.

At step 609, when the identified illuminance is lower than the designated illuminance, the processor 320 may change the position of the virtual image corresponding to the content to a second display region having a narrower view angle or FOV. The processor 320 may change the position of the virtual image corresponding to the content to the inside of the user (e.g., closer to the center axis of the user's FOV). In order to change the position of the virtual image corresponding to the content, the processor 320 may adjust the position and/or size of the content displayed on the display 360. The processor 320 may change the position of content displayed through the display 360 to an inside region. The processor 320 may decrease the distance between the image for the left eye corresponding to the content and the image for the right eye corresponding to the content.

When the identified illuminance is lower than the designated illuminance, the processor 320 may output the image in a third region that has been restricted compared to the first region.

At step 611, when the identified illuminance is the same as the designated illuminance, the processor 320 may maintain the position of the virtual image corresponding to the content. In other words, the processor 320 may abstain from changing the position and/or size of the content displayed through the display 360.

FIG. 7 is a flowchart of operations of the electronic device 301, according to an embodiment.

Referring to FIG. 7, at step 701, the processor 320 may identify the speed of the electronic device 301 using at least one of the acceleration sensor 315 and the GPS module 317.

At step 703, the processor 320 may compare the identified speed with a designated speed. The processor 320 may determine whether the identified speed is higher than the designated speed. The designated speed may be set by the user or automatically by the processor 320.

At step 705, when the identified speed is higher than the designated speed, the processor 320 may change the position of the virtual image corresponding to the content to a third display region having a narrower view angle or FOV. The processor 320 may change the position of the virtual image corresponding to the content to the inside of the user (e.g., closer to the center axis of the user's FOV). In order to change the position of the virtual image corresponding to the content, the processor 320 may adjust the position and/or size of the content displayed on the display 360. The processor 320 may change the position of content displayed through the display 360 to an inside region. The processor 320 may decrease the distance between the image for the left eye corresponding to the content and the image for the right eye corresponding to the content. Thus, the processor 320 may display content with a longer focal length than when the speed is lower.

At step 707, if the identified speed is not higher than the designated speed, the processor 320 may determine whether the identified speed is lower than the designated speed.

At step 709, when the identified speed is lower than the designated speed, the processor 320 may change the position of the virtual image corresponding to the content to a fourth display region having a broader view angle or FOV. The processor 320 may change the position of the virtual image corresponding to the content to the outside of the user (e.g., away from the center axis of the user's FOV). In order to change the position of the virtual image corresponding to the content, the processor 320 may adjust the position and/or size of the content displayed on the display 360. The processor 320 may change the position of content displayed through the display 360 to an outside region. The processor 320 may increase the distance between the image for the left eye corresponding to the content and the image for the right eye corresponding to the content. Thus, the processor 320 may display content with a shorter focal length than when the speed is higher.

At step 711, when the identified speed is the same as the designated speed, the processor 320 may maintain the position of the virtual image corresponding to the content. In other words, the processor 320 may abstain from changing the position and/or size of the content displayed through the display 360.

FIGS. 8A and 8B are diagrams of differences between view angle and visibility depending on illuminance, according to an embodiment.

Referring to FIGS. 8A and 8B, the processor 320 may determine a visible region corresponding to the illuminance identified through the illuminance sensor 312 and designate a display region based on the determined visible region.

FIG. 8A illustrates a visible region when a human retina perceives an image at higher illuminance (e.g., in the daytime). At higher illuminance, the human retina may perceive the image within a first visible region 810 of an entire region 801. In other words, the human retina may recognize an object within the view angle or FOV and/or visible distance corresponding to the first visible region 810.

The processor 320 may display content in the first visible region 810 based on the ambient illuminance of the electronic device 301. The processor 320 may change the position of the content displayed through the display 360 to the first visible region 810.

FIG. 8B illustrates a visible region when a human retina perceives an image at lower illuminance (e.g., in the nighttime). At lower illuminance, the human retina may perceive the image within a second visible region 820 of the entire region 801. In other words, the human retina may recognize an object within the view angle or FOV and/or visible distance corresponding to the second visible region 820. The second visible region 820 may have a narrower view angle and shorter visible distance than the first visible region 810.

The processor 320 may display content in the second visible region 820 based on the ambient illuminance of the electronic device 301. The processor 320 may change the position of the content displayed through the display 360 to the second visible region 820.

At the first speed, the human retina may perceive the image within the first visible region 910. In other words, the human retina may recognize an object within the view angle or FOV and/or focal length corresponding to the first visible region 910.

The processor 320 may display content in the first visible region 910 based on the speed of the electronic device 301. The processor 320 may change the position of the content displayed through the display 360 to the first visible region 910.

At a second speed (e.g., at a normal speed), the human retina may perceive the image within the second visible region 920. In other words, the human retina may recognize an object within the view angle or FOV and/or focal length corresponding to the second visible region 920. The second visible region 920 may mean a region having a broader view angle or FOV and/or shorter focal length than the first visible region 910.

The processor 320 may display content in the second visible region 920 based on the speed of the electronic device 301. The processor 320 may change the position of the content displayed through the display 360 to the second visible region 920.

At a third speed (e.g., at a lower speed), the human retina may perceive the image within the third visible region 930. In other words, the human retina may recognize an object within the view angle or FOV and/or focal length corresponding to the third visible region 930. The third visible region 930 may have a region having a broader view angle or FOV and/or shorter focal length than the second visible region 920.

The processor 320 may display content in the third visible region 930 based on the speed of the electronic device 301. The processor 320 may change the position of the content displayed through the display 360 to the third visible region 930.

Referring to FIG. 9, the human retina may recognize an object within a narrower view angle or FOV and shorter visible distance as the speed increases. Accordingly, the processor 320 may identify the speed and/or a variation in speed of the electronic device 301 and display content in the visible region based on the identified speed and variation in speed.

The processor 320 may gradually change the position of display of the plurality of contents 1011 to 1015 from the first display region 1010 to the second display region 1020 as per the variation in illuminance (or speed).

The processor 320 may adjust the size of the plurality of contents 1021 to 1025 displayed on the second display region 1020. As the position of display of the plurality of contents 1011 to 1015 varies, the processor 320 may display the contents 1021 to 1025 which are equal or smaller in size than the contents 1011 to 1015 used to be displayed in the first display region 1010 in the second display region 1020.

Referring to FIG. 10C, the processor 320 may display a plurality of contents 1031 to 1035 in a third display region 1030 based on at least one of the identified illuminance and speed.
